Proteins form an important nutrient in the human body. Made up of essential and non-essential amino acids, it helps in building and repairing muscles and bones, restoring body cells, providing a source of energy and controlling many of the important metabolism processes in the body.
Proteins are compounds composed of carbon, hydrogen, oxygen , and nitrogen , which are arranged as strands of amino acids . They play an essential role in the cellular maintenance, growth, and functioning of the human body. Serving as the basic structural molecule of all the tissues in the body, protein makes up nearly 17 percent of the total body weight. To understand protein's role and function in the human body, it is important to understand its basic structure and composition. Amino Acids. Amino acids are the fundamental building blocks of protein. Long chains of amino acids, called polypeptides, make up the multicomponent, large complexes of protein. The arrangement of amino acids along the chain determines the structure and chemical properties of the protein.
